Application filed February 3,1897. Serial No". 621,739. (No model.) 7 IT on whom it may concern:

Be it known that we, FRANCIS G. GIBBONS and ANTHONY J. GIBBONs, citizensof the United States, residing at Lewisburg, in the count y of Union andState of Pennsylvania, have invented certain new and useful Improvementsin Devices for Opening or Glosing Gates; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as Will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to a novel construction in a gate and devices foroperating the same; and it consists in the features of constructionhereinafter fully described and specifically claimed.

In theaccompanying drawings, forming part of this specification, Figure1 is a perspective view of a gate and devices for oper-- ating the samethat are constructed in ac-' cordance with this invention. spectiveview, taken on an enlarged scale, of the operating devices.

Referring now to the drawings, .1 indicates a gate-post, and 2 thelatch-post. The gate 3 is pivoted to the post 1 and provided at itsouter end with a latch 4 to engage the latchplate 5 of the latch-post 2and of the side post 6. The gate-post 1 is provided withforwardly-extending brackets 7, while the gate is provided withrearwardly-extending brack- ..ets 8. The outer ends of these brackets 7and 8 are provided with openings or eyes to receive the hinge-rod 9. Theupper and lower ends of the rod pass through the eyes of the brackets 7,while just below the upper bracket and above the lower bracket are thecranks 10, which pass through the brackets 8 of the gate. These cranks10 extend in opposite directions in the manner shown. The lower end ofthe hinge-rod 9 is provided with the arms 11, to which theoperating-rods 12 are fastened. The outer ends of these operating-rods12 are fastened to the crank-shafts 13, which are supported in bearingson a sill 14. The inner ends of the crank-rods 13 are provided with twostops 15, extending radially therefrom, while one end of the lever 16 ispivoted upon the rod 13 between the stops.

Fig. 2 is a per- The other end of the lever 16 is pivoted by means of abearing 17 upon the sill.

In Fig. 1 of the'drawings the gate is shown as closed-that is to say,with the upper crank 10 of the rod 9 situated adjacent to the gate, andconsequently the lower crank 10 on the opposite side thereof. It'isnoted that the brackets 8 differin length, so that in this po- Thesition the gate is practically horizontal. levers 16 stand in an uprightposition, which is caused by the counterbalancing-weight 18, fastened tothe lower end of the lever that is pivoted upon the rod 13, saidcounterbalancing-weight being sufficient to hold the lever 16 in anupright position. XVhen the'parts are in this posit-ion, it is seenthatthe stop 15 between the lever and the gate is also in an uprightposition and in contact with the side of the lever. It is seen,therefore, that when the lever 16 is moved toward the gate-for instance,by being run over bythe wheel of a vehiclethe shaft 13 is turned uponits axis,

which moves the rod 12 longitudinally, and

consequently turns the pivot-rod 9 a quarter of a revolution. This hasthe effect of withdrawing the latch from the latch-post, which causesthe gate to swing toward the post 6,

whereupon the latch engages the latch-plateupon this post. It is seenalso that the rod 12 on the other side of the gate, being drawn towardthe gate, moves the stop 15 on the outside of the lever against the sideof the same, and that consequently when the other lever is run over bythe wheel it will move the parts in a. reverse direction and thus causethe gate to be unlatched from the post 6, turned upon its pivot, andlatched with the post 2. It is also noted that assoon as the lever 16 isreleased the counterbalancing-weight 18 will raise it to an uprightposition.

7 Having thus described the invention, what is claimed as new is Thecombination with a gate and latch post,

brackets, oppositelyextending crank-arms In testimony whereof We havesigned this at the lower end of said hinge-1'od, rods eonspecificationin the presence of two snbserib- 1o neeted with said crank-arms andextending on ing witnesses.
